# Applications

An **application** is one product that uses the Platform API and SDKs.

## Fields (conceptual)

| Field | Role |
| --- | --- |
| `code` | Stable string id used by SDKs (`YOUR_APP_CODE`) |
| `name` | Human label in admin |
| `status` | Only `active` apps are served on public endpoints |
| Public key | `rb_pub_…` required for paywall and payments |
| Payments flag | Enables paid checkout for the app |

## Client identification

Every SDK request should identify the app via:

- Header `X-Application-Code: YOUR_APP_CODE` (default), or
- Header `X-Application-Id: <uuid>` when you prefer UUID

Plus, when required:

- `X-Public-Key: YOUR_PUBLIC_KEY`
- `Authorization: Bearer YOUR_ACCESS_TOKEN` for user-scoped routes

## What lives under an application

- Entitlements
- Plans / prices
- Paywalls
- Users (memberships)
- Devices
- Payments / subscriptions
- Remote config & feature flags
- Analytics events
